I can't remember where I read someone's theory that perhaps clusters are some strange sort of allergic reaction... or caused by one... Anyway, someone recently posted that she's had no clusters since her gallbladder was removed (she had gallstones). Anyway, maybe we're all reacting to something or combination of things that are triggered in various parts of digestive, CNS (central nervous system--the hypothalmous variation that we apparantly have--extra gray matter?)...
Maybe the brain variation comes at one time--after a concussion or perhaps is inherited sometimes--but the other triggers or assaults to the system that all have to reach some threshold come from different paths for different folks--smoking for some, rapid growth spurts for others, gallstones for others, head injuries for others?
Or on other hand, maybe I'm on too much predisone and can't get to sleep and my immagination is running away with me?
